A method for manufacturing a moisture impermeable element for pressure equalization a housing

The disadvantage of this known pressure compensating elements, that the Webstoffabdeckung used in this case must be fastened in additional processing steps and thereby can workmanship, in particular a non-continuous fastening, then nevertheless moisture can penetrate through the. DOLLAR A core idea of ​​the invention is that microfine openings can be introduced into the housing wall by laser drilling in the meantime, the diameter, a pressure equalization by these microfine holes is however possible approximately reached the mesh density of the woven fabrics used so far, thereby preventing the intrusion of water drops.
